- A lift station is to be designed to handle wastewater flows
ranging from 400 gpm to 1500 gpm. The influent sewer invert
elevation is 600 ft. The discharge line is 2,000 ft long with a
high point elevation of 625 ft. A wet well diameter of 10 ft is to
be used. Recommend the pump capacity, the number of pumps, and the
TDH.
Assume the following:
Maximum
number of pump starts per hour = 5
Hazen-Williams C = 100.
Hydraulic
losses in the pump station = 14 ft
Freeboard
allowance for influent sewer = 1 ft
